That approach suffers from the problem that all temporary objects
created during the build will be represented despite the fact they're
not in the document.  You might try a System.gc() but we've found here
before that it doesn't really do a full gc, if it does a gc at all. 
(Testing on JDK 1.2.2 Windows shows System.gc() does nothing.)
